Introduction to File Handling in Python

File handling is a mechanism for reading and writing data to disk files in Python programs.
It allows for the permanent storage of data in a file for future use.
The three steps in file handling are opening the file, performing read/write operations, and closing the file.
A file is a contiguous set of bytes used to store data, while file paths represent the location of a file and include the folder path, file name, and extension.
The open() function is used to open and read a file in Python, taking two parameters: filename and mode.
There are four different modes for opening a file: "r" for read, "a" for append, "w" for write, and "x" for create.
When reading files, the three main modes are reading (default), writing, and appending.
If a file does not exist, an IOError will occur during reading, while a new file will be created during writing or appending.
Methods for the file object include close(), read(), readline(), readlines(), and write().
String methods like isupper(), islower(), isdigit(), isalpha(), and isalnum() can be used to manipulate file contents.
Additional string methods include lower(), upper(), startswith(), endswith(), strip(), lstrip(), rstrip(), and join().
Reading and writing files can be done using the open() function and various methods, such as read(), write(), and append().
